Consistency Group Properties table

The following table describes the items in this table.

Item	Description
CTG ID	The SI pair's CTG identification number.
Status	The CTG status. Values: SI Used: The CTG is being used by SI. (VSP 5000 series) SIMF Used (CCI): SIz is using the CTG, and you are using CCI to manage the CTG. (VSP 5000 series) SIMF Used (PPRC/BCM): SIz is using the CTG, and you are using Business Continuity Manager (BCM) or IBM PPRC to manage the CTG. TI Used: HTI is using the CTG. (VSP 5000 series) Mainframe Reserved: The CTG is reserved for use by BCM or IBM PPRC. Free: The CTG is not being used and is not reserved. (Changing...): The status is in the process of changing.
Number of Pairs	The number of pairs assigned to the CTG.

Pairs table

The Pairs table shows pairs with a P-VOL or S-VOL allocated to you.

The following table describes the items in this table.

Item	Description
Primary Volume	The P-VOL information. Values: LDEV ID: The P-VOL's LDEV identifier. LDEV Name: The P-VOL's LDEV name. (VSP 5000 series) Emulation Type: The P-VOL's emulation type. Capacity: The P-VOL's volume capacity. CLPR: The P-VOL's CLPR ID. Virtual Storage Machine: The model type and serial number of the virtual storage machine to which the P-VOL belongs. Virtual LDEV ID: The identification number of the P-VOL's virtual LDEV. If no virtual LDEV ID is assigned, a blank is displayed. Virtual Device Name: The name of the P-VOL's virtual device, in a combined format of `virtual emulation type`, `number of virtual LUSE volumes`, and `virtual CVS attribute`. Each of these three items is displayed only if it is specified. If none of them are specified, a blank is displayed. "CVS" is displayed at the end of the device name, if the virtual CVS attribute is specified. Virtual SSID: The virtual SSID of the P-VOL. If no virtual SSID is specified, a blank is displayed.
Copy Type	The pair type. Values: SI-L1: SI L1 SI-L2: SI L2 TI: HTI (VSP 5000 series) SIMF: SIz
Snapshot Group	HTI pairs only. The snapshot group name. If you have not assigned the pair to a snapshot group, a blank is displayed. For non-HTI pairs, a hyphen is displayed.
Status	The status of the pair. For more information about pair status, see Device Manager - Storage Navigator pair status names and descriptions.
Snapshot Date	HTI pairs only. The date and time the snapshot was acquired. For non-HTI pairs, a hyphen is displayed.
Secondary Volume	The S-VOL information. Values: LDEV ID: The S-VOL's LDEV identifier. LDEV Name: The S-VOL's LDEV name. (VSP 5000 series) Emulation Type: The S-VOL's emulation type. Capacity: The S-VOL's volume capacity. CLPR: The S-VOL's CLPR ID. Virtual Storage Machine: The model type and serial number of the virtual storage machine to which the S-VOL belongs. Virtual LDEV ID: The identification number of the S-VOL's virtual LDEV. If no virtual LDEV ID is assigned, a blank is displayed. Virtual Device Name: The name of the S-VOL's virtual device, in a combined format of `virtual emulation type`, `number of virtual LUSE volumes`, and `virtual CVS attribute`. Each of these three items is displayed only if it is specified. If none of them are specified, a blank is displayed. "CVS" is displayed at the end of the device name, if the virtual CVS attribute is specified. Virtual SSID: The virtual SSID of the S-VOL. If no virtual SSID is specified, a blank is displayed.
Pool Name (ID)	HTI pairs only. The pool name and identification number. For non-HTI pairs, a hyphen is displayed.
Copy Pace	SI and SIz pairs only. The system option that determines the rate at which you want the storage system to copy data. For HTI pairs, a hyphen is displayed. Values: Slower: Improved host I/O performance but slower processing speed. Medium: Average processing speed and host I/O performance. Faster: Faster processing speed but slower host server I/O performance.
Mirror Unit	The mirror unit number.
Cascade	Indicates whether cascade pairs can be created. Enabled: Cascade pairs can be created. Disabled: Cascade pairs cannot be created. For non-HTI pairs, a hyphen is displayed.
Type	The pair type. Snapshot: The pair has the snapshot attribute. Clone: The pair has the clone attribute or diff clone attribute. In the TI Pairs window, if Diff Compare Volume displays the LDEV ID, the diff clone attribute is set for the pair. If Diff Compare Volume displays a hyphen (-), the clone attribute is set for the pair. For non-HTI pairs, a hyphen is displayed.
Topology ID	The topology ID, which indicates the layer of the pair based on the mirror unit. The topology ID consists of the LDEV ID of the volume (root volume for Thin Image pairs), which is the base of the target pair, and the mirror unit number.
